I have 1.5 year old Hayward pool motor that has recently developed some issues. I first noticed this a week ago when the pump was off during the day when it should be on. I looked at the circuit breaker and it was red. I flipped it back on and after 4-5 seconds of humming the motor started and functioned without any issues. It worked for 2 days and then the same thing. This time when I switched the circuit breaker back on it hummed for 4-5 seconds and flipped the breaker. I tried it again and it hesitated and then started. It keeps going through this cycle of working for a few days then not. I manually turned the impeller and it turns freely. I also tested the capacitor with a multimeter and it seems to be functioning. Anyone have an idea what may be causing this hesitation at startup with normal function thereafter?
